Forecast shows all of Wisconsin to dip below zero

MILWAUKEE — Another round of sub-zero temperatures are moving into Wisconsin on the tail of gusty winds.

Parts of southern Wisconsin, including Madison and Janesville, are under a winter storm warning into Monday morning, as high winds will create whiteout conditions.

The National Weather Service says temperatures are expected to dip to 9 below zero overnight, with wind chills between negative 20 and negative 30. Highs on Monday aren't expected to rise above 7 below.

The weather service says central and eastern Wisconsin will see similar temperatures Monday. Milwaukee Mayor Tom Barrett said in a news release that residents should take "appropriate precautions" against the frigid weather.

The weather service says northern Wisconsin's high temperatures will be near 13 below Monday, with wind chills ranging from 35 to 45 below.
